Method for the production of 2,3-dialkoxypropanals

The preparation of 2,3-dialkoxypropanals of the general formula I (I) in which R1 and R2 denote C1-C8-alkyl or C5- or C6-cycloalkyl which may or may not bear substituents which are inert under the conditions of the reaction, wherein a 1,2-dialkoxy ethene of the general formula II R1O-HC=CH-OR2(II) i...

Zusammenfassung:	The preparation of 2,3-dialkoxypropanals of the general formula I (I) in which R1 and R2 denote C1-C8-alkyl or C5- or C6-cycloalkyl which may or may not bear substituents which are inert under the conditions of the reaction, wherein a 1,2-dialkoxy ethene of the general formula II R1O-HC=CH-OR2(II) is reacted with carbon monoxide and hydrogen in the presence of a rhodium-containing catalyst.
